Abstract
A method, implemented by a distributed unit (DU) of a base station that also includes a central unit (CU), of handling small data transmission (SDT) with a user equipment (UE), includes receiving, from the UE while the CE is in an inactive state, a first message including uplink data (304). The uplink data includes control plane or non-control plane information. The method also includes determining, based on a logical channel with which the uplink data is associated, whether to transmit the uplink data to a control plane of the CU (CU-CP) or a user plane of the CU (CU-UP) (306), and transmitting the uplink data to cither the CU-CP (308) or the CU-UP (320) in accordance with the determining.
